Delhi Metro Rail Corporation (DMRC) has started trial runs on a 3.5-km stretch between the Kalindi Kunj Depot and Okhla Vihar Metro stations of the Janakpuri West-Botanical Garden line -- the first in phase 3.

During the trials, the interface of the metro train will be checked to ensure there is no physical infringement with civil infrastructure during its movement on the track. The subsystems of the coaches will also be tested.

“Later on, in stages, the new signaling technology to be implemented on this corridor and the communication-based train control (CBTC) will undergo rigorous testing,” said a DMRC spokesperson.

The response of the train at different speeds, braking and the interconnection with the operations control centre (OCC) will be monitored. The behaviour of the track system and the overhead electrification (OHE), where snags are often reported, will be checked repeatedly.

The total length of the corridor, called the magenta line, is 38 km (including the Kalindi Kunj–Botanical Garden part of 3.494 km). There will be 25 stations, of which 10 will be elevated and 15 underground.

According to DMRC, the estimated ridership is 3, 61,356 from Janakpuri West to Kalindi Kunj and 46,054 from Kalindi Kunj to Botanical Garden.
